The Carl Hayden Bee Research Center is located on a 5.3 acre tract deeded to the United States Dept. of Agriculture by the University of Arizona and is about 5 miles from the university's main campus in Tucson, Arizona.  The site allows for cooperation between Center personnel and the University staff.  Development of this facility was largely due to the efforts of Senator Carl Hayden.  In honor of his contribution, the Bee Research Laboratory was named after him on April 9, 1979.

The present building was completed in 1966 and is equipped with the most advanced technical equipment and instruments.  The main laboratory and office building covers more than one-third of an acre.  Also on the site are large greenhouses, smaller isolation greenhouses, a shop area, a large storage building, three auxiliary office buildings and two small service buildings.
